Hi Roberto:

The documentation you are referring to must be updated. The LP#1460177 RFE implemented this feature. Actually there is a test class that is testing this functionality in the CI [1][2].

Regards.

Hey folks,

Can you confirm if the metadata should work in an ipv6-only environment?

As I understand from this discussion on LP:1460177 and the fork of the discussion in many opendev reviews #315604, #738205 #745705, ..., it seems like it should work.

However, this comment in the openstack doc [1] has me questioning if it really works.
"There are no provisions for an IPv6-based metadata service similar to what is provided for IPv4. In the case of dual-stacked guests though it is always possible to use the IPv4 metadata service instead. IPv6-only guests will have to use another method for metadata injection such as using a configuration drive, which is described in the Nova documentation on config-drive."

Is anyone using metadata in an ipv6-only Openstack setup?

Regards,
Roberto
